IMPROVEMENT IN TUCK-CREASERS FOR SEWING-MACHINES.

Specification forming partof Letters Patent No. 143,975, dated October28, 1873; application filed May 24, 1873.

To all whom it may concern:

Be it known that hwnmrnn J FAULKNER, of Chicago, in the county of Cookand State of Illinois, have invented a new, useful, and ImprovedTuck-Marker for Sewing-Machines, of which the following is a full,clear, and exact description, which will enable others skilled in theart to which my invention appertains to make and use the same, referencebeing had to the accompanying drawing forming a part hereof, and inwhich- Figure 1 is a side elevation of my improved tuck-marker, and Fig.2 a front elevation of the same. 7

Like letters of reference indicate like parts.

My invention relates to that class of devices employed in connectionwith sewing-machines for the purpose of readily marking the cloth toindicate the proper position of the fold during the operation oftucking.

The object of my invention is to improve the construction and operationof devices of this class; and to that end it consists in certain novelfeatures, hereinafter fully described and particularly set forth,relating to the construction of the marker.

In the drawing, A represents the bed-plate of the marker. a is a thinvertical or nearly vertical blade, projecting upward from the forwardpart of the bed-plate, and lying longitudinally in the direction inwhich the cloth moves during the operation of the machine. The upperedge of the blade to is SLlffiOlGlltlY sharp to make a distinct mark,but not so sharp as to cut the cloth, and it is also slightly inclinedor rounded, as shown in Fig. 2, so that the cloth will readily ride uponit without being injured. The bed-plate is provided with an ordinarygage, and is attached to the machine in the usual manner. B is aspring-arm, attached to the rear part of the bed-plate, and extending toor beyond the blade at. The forward end of the arm Bis coiled, so thatan inverted \l-shaped space, (1/, arranged toreceive the blade at, willexist between the coils, as shown in Fig. 1. The arm B is then ex tendedso as to form an arm or lever, B, arranged in the manner shown, and forimpinge nient by the spring-arm G, which is actuated by the needlebar inthe usual manner. The natural position of the arm B, when not i1npingedby the arm O, is such that the space a, which is inclined from the bladeit toward the arm B, will be slightly above the blade. As the arm B ismoved downward the widest part of the space a first laps the cloth, thusfolding the latter over the edge of the blade. As soon as the downwardmovement of the arm B is sufficiently resisted the said arm begins toroll on the cloth, owing to the action of the arm 0 on the lateralextension B, and thus not onlyfolds the cloth over the edge of theblade, but rubs the cloth and presses it against the lateral faces ofthe blade until the end of the space a is reached,thus making a distinctcrease or mark for the fold or tuck.

It will be perceived from the foregoing description that the marker isat all times adapted to cloths of various thickness.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A tuck-marker provided with the blade a, and with the yielding androlling arm B provided with the inclined space a, arranged above theblade (1, and with the lever B extending laterally from the said arm,substantially as and for the purposes specified.

2. In a tuck-marker the combination and arrangement of the blade a,coiled-spring arm B provided with the inclined and inverted V-shapednotch a, and arm or lever B, and arm 0, all substantially as and for thepurposes specified.
